To all whom it 'may concern.

Be itknow'n'that I, THOMAS OQBEAUMO-N'I,

-'a citizen of the United States, residing in the city, county, and'State of New York, have invented certain new and useful Improvements in Flushing-Tanks, of which the following is This invention relates to certain improvements in flushing tanks for water closets or the like, the invention being directed to means for rendering the tank noiseless inoperation, and to meansfor supporting and guiding the valve and overflow pipe.

Figure 1 of the accompanying drawings is a'vertical longitudinal mid-section through the tank and valve. Fig. 2 is a vertical transverse section on the line 22 in Fig. 1, looking toward left. Fig. 3 is a fragment of Fig. 1 showing the valve lifted. Fig. 4 is a plan of the valve seat showing the valve tube in section. 1

Let A designate the tank or cistern; B, the flushing pipe leading down therefrom; O, the water supply 'pipele'ading thereto; D, the float valve or cook for controlling the admission of water; D, the hush-pipe through which the,

water enters the tank from the float-valveg F, the float controlling the float-valve; G, the operating lever of the tank; E, the outlet valve thereof, andH the overflow pipe.

these parts areor may be all of any usual or known construction.

The valve E. is essentially a disk having a soft seating face or packing which closes upon the annular seat a forming the margin of an outlet shell I which extends down through the bottom of the tank, and to the lower end of which the flushing pipeB is coupled in the. usual manner.

The overflow pipe H consists of a tube open at top, slightly above the normal water level, and passing down through the valve E, being formed with a downward extension lettered H beneath the valve, and projecting into the outlet shell I). The overflow pipe H consequently lifts with the valve E,,the two being rigidly connected. The valve E is constructed with a disk 0, having a neck screw- Except in the particulars hereinafter stated,

ing uponjthe lower end of the overflow pipe H, and an outwardlyprojecting flange, against which flange the soft valve face or packing disk dof leather or rubber is clamped by a flange e, which is formed on the extension tube Hf, which tube is screwed on the lower endof the overflow pipe H to form an uninterrupted continuation thereof for the descent of the overflow water.

The valve-stem Iconsists of a rod or. wire extending down through the pipe H, and connected at its lower end to a cross-bar f formed within the lower end of the pipe Hor the valve E. Its connection is preferably a loose one, and the stem I being thus connected centrally to the valve at its lower end, is maintained concentrically within the upper portion of the tube H by means of four outwardly turned arms 9 formed on a tube h, which is fastened onto the valve-stem I, these arms 9 being formed with ample interstices between them to permit the downflow of the overflow water.

The upper end of the stem I is hooked into the lever G, the opposite arm of which is connected to the usual pull-chain 2'.

Directly over the open top of the overflow pipe H isrnounted a hush-plate or disk J, in such position that when the valve is lifted the lifting movementof the overflow pipe will by the overflow pipe and remains resting on' the top thereof during the time that the valve is open, as shown in Fig. 3. For thus mounting the hush-plate, it is provided with a tubular neck or stem j, on the upper end of which is fixed a nut or disk or other overhanging part It, and the tank is provided with a bracket 'plate or arm J, best shown in Fig. 2, through a hole in the end of which the neck j freely passes, and on the top of which the head it rests, so that in the normal position of the other way the open overflow tube communi-t cates with a flushing pipe, itis found that the descending stream of flushing water creates a suction which draws air down through the overflow pipe and mingles it with the stream of flushing water, so that it creates a disagreeable sucking noise in the tank. It is to overcome this noise that I have providedthe hush-plate J, which when the valve is lifted serves to close the upper end of the overflow pipe shown in Fig. 3, and thereby prevents the inflow of air along with the flushing water. Bylconstructing the plate J so that/it is freely hung or suspended from the support K,

itispermitted to adapt itself to the top of the overflow tube so as to make a su fficien tlyclose I joint therewith without the necessity of any fine finish for the parts, or the use ofany soft packing, it not [being essential to absolutely exclude all air, butsimply to prevent the inrush of enough air to cause the sucking noise referred to.

I will now describe the means for guiding flow pipe and keeping it in vertical position,

the valve-stem I where it projects above this pipe passes through the tubular stem or neck j of the hush-plate, which itself is heldin position for passing through the hole in the end, of the supporting arm or bracket K. Since the valve-stem I is guided concentrically within the overflow pipe H, and is itself held centrally by the tubular stem j and its sup:

port K, it is apparent that the upper end of the overflow pipe will be thus guided or centered.

I claim as my invention the following-defined novelfeatures, substantially as hereinbefore set forth, namely:

1. A flushing tank having an outlet valve with an open-topped overflow pipe passing through and movable with it, combined with a hush-plate J suspended above said, pipe and having-a neck-j and head 70, and with a supporting arm K having a hole through which said neck passes and on which said head rests for suspending the hush-plate, so that the latter can be lifted when encountered by the overflow pipe upon the opening movement. of the valve.

2. A flush-ing tank having an outlet valve with an open-topped overflow pipe passing through and movable with it, and a stem projecting up above said; pipe, combined with a hush-plate J suspendedfabove said pipe hayinga tubular neck j through whichsaid valve; stem passes, and a supporting arm for uphold ing the hush-plate having a guidingopening;

embracing said tubular neck, whereby the valve stem is concentrically guided in said opening by means of said tubnlarneck.

3. A flushing tankhavingan outlet valve with an overflow pipe passingthrough and movable with it, constructed with meansfor guiding said I valve and joverfliOW Pipe, at top and bottom, consisting of; an outlet shell I having internal projecting guidingribs ZZembracing between them the downward extension of said overflow, pipe. beneath the valve, the valve-stemI concentrically guided'within said.

pipeand projecting above its upper end, a

hush-plateJ suspended above said pipe and having a tubular neckj through which said valve-stem passes and by which it is guided, and. a supporting armor bracket K. from whichsaid hush-plateis hung, having anopen: ing embracing the tubula r neck thereof.

In witness whereof Ihave hereuntosigned' my name in the presence of two subscribing witnesses.
